How to Use async let

Run async tasks in parallel.

Steps

  1. Paste the code into a Swift file or playground.
  2. Run it once to verify the output.
  3. Adjust the inputs to match your use case.

Copy and paste

import Foundation

func loadUser() async -> String { "User" }
func loadSettings() async -> String { "Settings" }

Task {
    async let user = loadUser()
    async let settings = loadSettings()

    let result = await "(user) + (settings)"
    print(result)
}

Notes

  • Keep functions small and focused for reuse.
  • Prefer safe APIs like optionals and guards.
